BN7000SUMIBORON for Cast Iron/Sintered Alloy Machining
K Sintered
For high-speed finishing of cast iron, Sintered alloys, and difficult-to-machine materials!
- General Features Medium-grain CBN sintered to a high density to achieve the maximum content percentage. Also delivers superior fracture resistance by increasing the binding strength between CBN particles. Provides stable, long tool life for high-speed finishing work with cast iron, Sintered alloys, and difficult-to-machine materials.
Acid-treated CBN Sintered Body Structure
BN7000 Competitor's CBN for Cast Iron
Holes made by the binder melting from the acid treatment.
Few Holes Many Holes
- Characteristics Excellent for high speed finishing of Cast Iron!
Good wear and fracture resistance in high speed machining of Gray Cast Iron.
- High efficiency machining of Sintered alloys With 4 different types of edge treatment, stable and long tool life can be achieved from machining of Sintered Alloys of any shape or hardness.
- Able to machine any Exotic Alloys. Long tool life can also be achieved for the machining of exotic Alloys such as Roll, HSS and Heat-Resistant Alloy etc.
- Cutting Performance
